To apply the DSM-IV criteria for PMDD women must chart symptoms daily for at least two cycles, and their chief complaints must include one of the four core symptoms (irritability, tension, dysphoria and lability of mood) and at least five of the 11 total symptoms. The symptoms should have occurred with most menstrual cycles during the past year and have interfered with social or occupational roles. In addition, the charting of troublesome symptoms should demonstrate clear worsening premenstrually and remit within a few days after the onset of menstruation.
